Finally tall ; brancHets slender ; leaves scattered, sickleshaped-lanceolar, not very long, 

 rather more shining above than below ; their lateral veins very subtle and numerous, usually more 

 erect than transverse, the circumferential vein somewhat removed from the margin of the leaf ; 

 oil-dots copious, more or less pellucid ; umbels axillary or mostly lateral, bearing from 5 to 15, 

 rarely 3 to 4 flowers ; stalk slender^ slightly compressed ; stalklets considerably shorter than the 

 calyx ; lid broad-conical, acute, about as long as the semiovate tube of the calyx, the latter not 

 angular ; stamens all fertile, inflexed before expansion ; anthers kidney shaped, opening by 

 divergent sKts ; style capillary ; stigma not dilated ; fruits usually small, truncate- or globular- 

 ovate, contracted at the narrom-edged orifice ; valves perfectly enclosed, 3 or much oftener 4, 

 deltoid ; sterile seeds mostly not much narrower than the fertile seeds, all without appendage. 



On less fertile ground, from the coast to mountain-regions, occurring even on sand-lands, in 

 Gippsland and New South Wales. 



The White Stringybark of the colonists, called by the G-ippsland natives, with E. macrorr- 

 hyncha and E. capitellata, " Yangoora." 



Trunk to as much as 4 feet in diameter. Stem and branches covered with fibrous outside 

 grey and rough bark. Seedlings smooth, with oval- or oblong-lanceolar or broad-oval leaves, the 

 lower of these opposite, the upper ones scattered. Leaves of the advanced tree dark-green, usually 

 of rather thin consistence. Umbels often crowded, never terminating the branchlets, now and 

 then paniculated, but in such a case still lateral. Fruits occasionally larger and less roundish 

 than illustrated in the lithogram, with their edge sharp, which is not well shown in the litho- 

 graphic drawing. 



E. piperita differs from E. pilularis chiefly in its rough bark extending to the branches 

 (Pachyphloiee), more slender and less angular branchlets, more distinctly developed oil-glands of 

 the foliage, not so much compressed flowerstalks, smaller flowers with hardly any tendency to 

 aggregation into terminal panicles, fruits mostly smaller and at the orifice contracted with an 

 acute rim and evidently sunk valves. 



E. eugenioides (Sieber, in Sprengel curee posteriores 195), which extends from near Port 

 Phillip to South-Queensland and ascends the higher Alps in a dwarfed state, shares in some of 

 the characteristics of E. piperita and in others of E. pilularis ; but its seedlings are hairy-rough, 

 and the edge of the fruit is blunt, with the valves situated near it, reminding more of the fruits of 

 E. hfemastoma. The scabrous seedlings depicted in the background of the lithogram of E. piperita 

 belongs to E. eugenioides, which is considered by Bentham a variety of that species. 



E. obliqua is distinguishable from E. piperita by its larger and thicker leaves of equal 

 shining color on Ijotli sides, witli more prominent and less divergent veins and with stomata rather 

 more cc|Uiil in number on eitlier page, by its umbels never so much crowded, by the sliorter and 

 roundcd-bluut lid, the longer and conically attenuated tube of the calyx, the sonievvliat longer 

 fruits and perhap.s by anatomic, histologic and chemical peculiarities of the bark and wood, wliiuli 

 characteristics remain yet more comprehensively to be studied.
